SPECIALTY CORPORATION, OF DETROIT, MICHIGAN, A CORPORATION OF HIOHIGAN BOILER CLEANER Application filed August 11, 1980. Serial No. 474,483.

My invention relates to new and useful improvements in boiler cleaners and is designed specifically for use in that class of boiler cleaners by means of whlch a cleaning fluid is discharged against the surfaces to be cleaned.

One of the objects of my invention is to provide a rotary boiler cleaner in Wl'llCh the cleaning fluid will be supplied to the cleaner 1 just before the cleaner begins the cleaning rotation. Another object is to provide such a cleaner in which the valve will be open during the entire cleaning rotation or rotations of the cleaner. Other objects will appear hereinafter. The'invention consists in the combinations and arrangements of parts herein described and claimed.

The invention will behest understood by reference to the accompanying drawings forming a part of this specification and in which:

igure 8 is a sectional view taken substantially on the line 88 of Figure 7;

Figure 10 is a sectional view taken substantially on the line 10-10 of Figure 9; and

Figure 11 is a detail sectional view taken substantially on the line 1111 of Figure 9'.

The preferred form of construction consists of a blower unit or perforated pipe 10 which is swivelly mounted in .a head 11. 50 Rigidly mounted upon the member 10 adjacent the end which is positioned within the head 11 is a gear 12 which meshes with a smaller gear 13, both of said gears being p0- sitioned within the head 11. The gear 13 is rigidly mounted upon one end of a shaft 14, upon the opposite end of. which is-rigidly mounted a sheave wheel 15. Positioned upon the sheave wheel 15 is a flexible element which is preferably a chain. As will be readily understood the wheel 15 ma be rotated throu h the chain 16 and there y rotation of the lower unit 10' is brought about.

In the operation of cleaners of this class the fluid most commonl' used is steam. The head 11 is provided ad iacent its under surface with an opening with which communicates a supply pipe 17 which communicates with a suitable source of supply of cleaning fluid. The head 11 is provided with a suitable opening 18 which communicates with the supply pipe 17. In this opening 18 is positioned one end of the blower unit or perforated pipe 10, permitting the blower unit to extend forwardly of the head 11 and into the interior of the boiler setting.

Formed in the rear of the head 11 is an opening 19 which communicates with the opening 18. Positioned in this opening 19 is a suitable piston head 20 provided with a shoulder or stud portion 20 to which is attached a. valve 21. As shown in Figure 3, the valve 21 is surrounded by the opening 22 so that fluid entering the head through the pipe 17 is allowed to circulate around the entire valve. A spiral spring is positioned within the head, one end of said spring 23 resting against the piston head 20. The opposite end of said spring 23 engages a cap 24 which is secured to the head 11 by means of bolts 24 and serves as a closure for the opening 19. Piston rings 25 are positioned upon the piston head 20 and serve to prevent any escape of cleaning fluid around the piston head.

The piston head 20 is movable in the opening 19 and when moved to its forward position causes the valve 21 to rest upon a valve seat 26 and thereby closes communication between the opening 18 and the supply pipe formed in the cap 24.

17. This is the normal position of this valve, the spring 23 serving to retain the valve in its normally closed position. In order to open the valve it is apparent thatthe piston head 20 must be moved in the opening 19 so as to compress the spring 23.

Positioned within a pocket formed in the cap.24 is a valve 27 provided with a valve stem 28 which projects exteriorly of the cap 24. Formed in the head at one side there is a passage-way 29 which communicates at one end with the opening 22 and at 1ts opposite end with an opening 30 formed in the cap 24. This opening 30 communicates with a passage-way 31 which 0 ens into the pocket ball valve is provided in the open end of this passage-way 31 so as to close this end of this passage as will be readily understood. Formed in the cap 24, diametrically opposite the passage 31 is an exhaust passage 34 which provides a conmotion between the pocket formed in the cap and the exterior of said cap. The valve 27 which is in the nature of a disc is positioned in the pocket formed in the cap and is provided on its periphery with a pocket 33, communicating with which are peripheral bleed passages 37. Formed in the valve 27 is an additional pocket 35 communicating with which are bleed passages 36. It is to be noted that these bleed passages 36 terminate at a point which is substantially diametrically opposite to the pocket 33.

When the pocket 33 is in alignment with the passage 31 the ball valve '32 serves as a closure for the passage 31, the ball 32 projecting into the pocket 33. When such a condition exists the bleed passages 36 will be in communication with the exhaust passage 34 and thereby the steam contained within the opening 19 will be exhausted. The pocket 35 communicates with open space 19 by means of a forwardly projecting passa e 35'. Upon turning the valve so that the ball valve 32 rides on the periphery of the valve 27, the passage 31 is in communication with bleed passages 37 thereby allowing the steam to enter opening 19 through the pocket 33. The pocket 35 is then in alignment with the passage 34. The steam entering space 19 flows through the passageway 35 and into the pocket 35 forcing the ball B, which is positioned in the pocket 35, against the end of the passage 34 so as to close the exhaust.

This is the normal position of the valve when the blower is not being operated. It is to be noted that when the valve 27 is in its normal position the steam from the supply pipe fills the opening 19 and the opening 22 so that pressure is exerted upon both sides of the piston head 20. When such is the case the spiral spring serves to assist the steam pressure to retain the valve 21 against the valve seat 26. When the valve is so positioned as to allow the ball 32 to project into pocket 33 the bleed passages-36 communicate with the exhaust passage 34 and the steam contained in the opening 19 is allowed to escape. When such is the case the steam pressure from the pipe 17 is exerted on theforward side of the piston head 20 and forces the same rearwardly against the pressure of the spring 23. This opens communication between the pipe 17 and the blower unit 10.

To provide means for operating this valve so that steam or other cleaning fluid will be admitted to the blower unit during the rotating of the unit, a bar 38 is securely fastened to the head 11 by means of bolts 38'. To the opposite ends of this bar 38 is .pivotally mounted a sleeve or guide member 39 and 39' respectively through each of which chain 16 pro ects after passing around or over the wheel 15. A stud projects forwardly from each of said sleeves, said stud 40 being threaded at its end and projected through the member 38. A suitable nut 41 is provided for securing this threaded end in position relative to the bar 38. Rigidly attached at one end to the member 39 is a link 42, the opposite. end of which is pivoted to one end of a link 43, the opposite end of said link 43 being rigidly attached to the valve stem 28. Attached to the sleeve 39, at one end, is a link 44, the opposite end of said link being pivotally secured to the link 43 at the point at which is attached the link 42, there being a longitudinal slot connection between the links 42 and 43. It is apparent that upon swinging the free ends of said sleeves-so as to recede from each other the valve stem is caused to turn. It is also apparent that any downward strain exerted upon the depending end of chain 16 will cause the sleeves to recede from each other at their free ends.

When the blower unit is to be rotated counter-clockwise in Figure 1, by rotating the sheave 15 clockwise in that figure, the operator pulls on the right-hand part of the chain 16. The initial pull swings the sleeve 39 on its pivot 40 against the pressure of spring 45, because of the normal angular position of the sleeve in relation to the downwardly extending chain and because the resistance to rotation of the unit and therefore of the sheave 15 provides a temporary holding of the upper end of the chain 16. This instantly causes valve 21 to be unseated by the pressure of the steam from the pipe 17 and consequently the steam flows into the blower unit. Continued pulling on the chain 16 rotates the sheave 15 and the unit- The parts preferably are proportioned so that the sleeve 39 is vertical when the arm 43 and the valve 27 have been rotated to bring the space 19 into communication with the exhaust port 34, so that the chain may pass freely through the sleeve in a substantially straight line. Obviously, so long as the chain 16 is pulled,

the valve 21 willremain open because the sleeve 39 will be held in its vertical position. i

If the unit is to be oscillated, instead of being continuously rotated in one dlrection, it will be obvious that the left-hand part of the chain 16 in Figure 1 must be pulled. If the right-hand part of the chain is released before the left-hand part is pulled, the spring 45 will return the parts to the position of Figure 1 and cause the valve 21 to close. As soon as pull is exerted on the left-hand part of the chain, however, the valve 21 will again be opened just before the unit begins its return rotation.

Obviously, if desired, this closlng and opening of valve 21 between each change of direction of rotation of the unit may be avoided b holding the two parts of the chain 16 at all times under at least enough pressure to prevent the operation of the spring 45. Then as the pulling pressure is transferred from side to side of chain 16, the valve 21 will remain open.

It will also be noted that the valve 21 may be opened by merely swinging the right-hand part of the chain sidewise to the right in Figure 1 without pulling on it, this sidewise mo,- tion opening the valve 21 and then the chain may be pulled to rotate the unit. When so operated, however, the valve 21 will be opened before the unit begins to rotate, precisely as when the chain 16 is merely pulled downward. It will also be obvious that, because of the shifting of the position of the sleeve, the chain 16 is swung bodily to the right of Figure 1, even when the chain is pulled to start the operation. In other words, whether the chain is first swung to the right and then pulled, or whether the operator merely pulls on the chain, the parts are moved to the same position, the sleeve 39 swinging on its pivot and the chain moving to the right of Figure 1.

While I have illustrated and described the preferred form of construct-ion for carrying my invention into effect, this is capable of variations and modifications without departing from the spirit of the invention. I therefore do not wish to be limited to the precise details of my invention, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

The foregoing is a continuation of my application No. 424,612, filed Nov. 17, 1920. In

place of the structure above described, the structure disclosed in application Serial No. 612,766, filed Jan. 15, 1928, in which I .am named as co-inventor with Norman L. Snow and Curtis L. Howse, may be used.

. Describing first in detail the particular embodiment shown in Figures 7 and 8, A designates a rotatable blower pipe or blower unit having discharge nozzlesB adapted for discharge of steam or the like therethrough for cleaning the surfaces of the boiler tubes C orother surfaces to be cleaned.

The blower ipe A receives its steam through ports 1?, these ports communicating through the chamber A with the stationary steam inlet B. For closing the communication of ports A with inlet B there is provided a valve D adapted to engage a seat D. The valve D is carried by the valve stem D and is operated by turning the sheave'or hand-wheel E in the following manner: This sheave wheel E is fixedly secured to the shaft F so that when the sheave wheel is revolved the shaft F also revolves.

Assuming that the valve D is against its seat D the wheel E is revolved to the right. This also turns the worm G which is fixed on the shaft F. The worm G meshes with the worm gear G. The latter, however, inthis position of the parts is prevented from revolving due to the fact that it is held by the dog H which engages a slot H in the worm gear hub. The continued operation of revolving the wheel E to the right resultsin the wheel E, shaft F and worm G being moved forward as the shaft F carries the valve stem D in opening the valve D from its seat D. When,

however, the shoulder F on the worm G abuts against the inner face F of the worm gear housing this prevents further movement longitudinally of the worm and the valve. However, the proportion of parts is such that at this time the dog H has become disengaged from the slot H.

The mechanism for disengaging the .dog consists of a lever H pivoted at H and having a projecting end H extending into a slot E As the shaft F is fed forward the shoulder of the slot E will force the projecting end H of the lever H forwardly and thus rock the locking dog H to a position where it will clear the slot H. Further rotation of the handle E to the right will then revolve the worm gear G, the locking do'g H being held out during the further rotation of the wheel E. The blower'is then reversed by turning the wheel E in the left-hand'direction but the shaft F cannot move longitudinally due to the fact that it is held in by the dog H riding on the surface of the hub H The blower pipe will then be revolved in the left-hand direction until the slot H comes back into registration with the dog H.

When this registration of the dog H and the slot H again takes place the dog comes in contact with the lug E which holds the blower pipe from further rotation and immediately the stem F starts to move to the right'and continues this movement until the valve D is brought tightly against the seat D. It will be noticed that this novel arrangement is not only used for rotating the unit and adjusting the valve but that the unit is positively held from rotation both v crating member is embodied in the construction shown in Figures 9, 10 and 11.

Describing more in detail this modified form, J designates the stationary supply pipe,

which through the passage J and port J connects to the interior of the valve cage. The length of the periods of admission of steam to the interior of the valve cage J is controlled by a plate J which can be adjusted for the various installations right at the place of installation by cutting oil a por-' tion of the plate to secure the desired opening in the port or slot. The actual admission of steam to the blower unit is, however, controlled by a valve K carried by the rotating shaft K.

On the outer end the shaft K is provided with screw threads K upon which there is loosely threaded the sheave wheel L. The latter carries a set of combination thrust and radial ball bearings L which prevent the sheave from moving in and out. The shaft K is also provided with four grooves M. Cooperating with these grooves in the manner hereinafter described and mounted in a suitable housing M carried by a stationary part of the blower structure, are locking dogs M and M normally pressed toward the grooves by springs M and M The dog M is provided with a groove engaging portion M". It will be noted that the groove engaging portions M and M are out of alignment so that the groove engaging portion M will come to the end of its groove in advance of the groove engaging portion M when the shaft is moved toward the left. For steadying the dogs M and M suitable members M may be threaded through the housings M for engagement in grooves M formed in the dogs. For opening the valve the sheave wheel L is revolved in the right-hand direction. However, in this position the locking dog M fitting in one of the slots M will prevent the shaft K from rotating. The sheave L through the screw threads K will then act as a nut to feed the shaft K outward which will result in moving the valve K away from its seat K This openingmovement will continue until the dog M reaches the incline N where it starts to rise out of the groove and finally rests on the outer surface of the shaft K. In this position the shaft K is free to revolve and at the same time the shoulder O on the shaft K comes into contact with the shoulder O on the sheave wheel preventing the screw and shaft K from running any further outward. In eifect that locks the sheave L and shaft K together T and the val-ye cage J as the sheave L continues to be rotated in a right-hand direction.

After the shaft K is free to revolve the continued movement in the right-hand direction of the sheave L will rotate the blower pipe Q. so as to properly direct the steam from its jets Q against the surfaces of the boiler tubes R or at the surfaces to be cleaned. Vanes or splines S on the shaft are provided so that a longitudinal movement can take place between the shaft K the driver part I After revolving the blower pipe through the desired are of rotation, the sheave wheel is then revolved in a left-hand direction. When the wheel is 1'0- tated in a left-hand direction the shaft K is locked from rotation by the engagement of dog M in one of the slots M. Continued rotation of the sheave wheel L in a left-hand direction will then feed the threaded portion or worm K of the shaft inward, moving the shaft K and the valve K until the latter is finally seated against its seat K. In this last described construction it will be noted that the right-hand movement only of the sheave wheel is utilized for rotating the unit whereas in the construction shown in Figures 7 and 8 the initial right-hand movement opens the valve and the continued right-hand movement of the wheel rotates the unit and it is then rotated back during the initial lefthand rotation of the wheel. In each of the last two described constructions, however, it will be noted that the unit is locked from rotation while the valve is being opened and closed so that a positive mechanical operation of the valve takes place which cannot be effected by steam pressure or other factors. For the sake of convenience the invention has been describedas being embodied in a boiler cleaner for cleaning parts of a boiler. It will be apparent, however, that the invention-may be embodied in any similar cleanin device, and it is to he therefore understood that the term boiler wherever used throughout the specification and claims is to be construed as meaning a fluid heater or heat transfer apparatus of any character while the term boiler cleaner is to be construed as meaning a cleaner for any such apparatus.

In this application no claims are directed to the specific structure shown in Figures 7 to 11, inclusive, since this specific structure is claimed in the said application, Serial No. 612,766, filed Jan. 15, 1923, in which application I am named as co-inventor with Norman L. Snow and Curtis L. Howse. Claims to the broad subject matter of these figures, however, are included in this application as well as claims specific to the structure shown in Figures 1 to 6, inclusive.

It-might be further noted that in this application no claims are directed to the mechanism providin for utilization of the cleaning fluid to e ect an actuation of the valve,

claims to this feature being incorporated in my co-pending divisional application Serial No. 348,093, filed March 18, 1929.

\Vhile several forms of the inventive idea have been disclosed in this application, it is to be understood that the description is illustrative only and is not definitive of the limits of the inventive idea. The right is reserved to make such changes in the details of construction and arrangement of arts as will fall within the purview of t e attached claims.
